Specification of Letters Patent,

Patented Jan. 15, 1907.

Application filed April 11 1906. erial No. 311.126.

To all whont it may concern/.2

Be it known that I, FRANCIS M. CAIN, a citizen of the United States, residing at Wesner, in the county of Woodward and Territory of Oklahoma, have invented a new and useful Metallic Railroad-Tie'; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make. and use the same.

The invention relates to metallic railwayties, and has for its object to provide a device of this character composed entirely of metal and which will firmly hold the flanges of rails against spreading or being upset when under great strain.

In the drawings forming part of this specification, Figure l is a perspective view of one end of a metallic tie constructed in accordanoe with this invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2.

Referring to the drawings, 1 designates the main body of the tie, having an integral jaw 2, which cooperates with an adjustable jaw 3 in firmly clamping the baseor flange of the ordinary T-shaped rails for either street-cars or railways. The adjustable jaws 3 have side portions or webs 4, which are provided with inwardly-projecting dovetailed tongues 5, which engage dovetailed grooves in the tie. These dovetailed tongues hold the adjustable jaw firmly against vertical movement. The adjustable jaw is held in engagement with the rail by a threaded bolt having a wedgeshaped portion 6, which when the rail wears loose from continued use can be adjusted to firmly clamp the same.

In practice the tie will rest upon a bar (not shown) laid in a parallel line with the rails, which will render the bolt accessible and which will prevent the tie from sinking into the sof t ground or bed.

What I claim is r 1. A metallic railway-tie, having an inner integral jaw, an adjustable. jaw cooperating therewith, and a bolt having a wedge-shaped portion engaging said adjustable jaw.

2. A metallic railway-tie, having an integral j aw, an adjustable jaw cooperating therewith, said adjustable jaw having depending side portions, inwardly projecting tongues formed integral with said side portions and engaging grooves in said tie, and a bolt hav ing a wedge-shaped portion to prevent lateral movement of said adjustable jaw.

3. A metallic tie having an integral jaw and an adjustable jaw, a pair of longitudinal grooves formed in the end portion of said tie, said adjustable jaw being substantially U- shaped and having tongues engaging said grooves, and a bolt having a wedge-shaped portion forpreventing lateral movement of said j aW.

In testimony whereof I have hereto afiiXed my signature in the presence of two witnesses.

FRANCIS M. CAIN.
